* tests/unixInit.test (unixInit-2.8): Changed test back to using
installation layout, adding comments explaining why the test writes to the directories it does, and checks to avoid destroying other files in /tmp.

+ # Checking for Bug 219416
+ # When a program that embeds the Tcl library, like tcltest, is
+ # installed near the "root" of the file system, there was a problem
+ # constructing directories relative to the executable. When a
+ # relative ".." went past the root, realtive path names were created
+ # rather than absolute pathnames. In some cases, accessing past the
+ # root caused memory access violations too.
+ #
+ # The bug is now fixed, but here we check for it by making sure that
+ # the directories constructed relative to the executable are all
+ # absolute pathnames, even when the executable is installed near
+ # the root of the filesystem.
+ #
+ # The only directory near the root we are likely to have write access
+ # to is /tmp.
